For designing audio interactions in everyday devices, which considerations about cognitive load and aesthetics must be kept in mind?

Question

Accepted Answer

A: Audio is linear, time-sensitive, and transient, therefore good design must limit the number of audio menu options. | B: Users will often listen to all choices before picking one, and a long list limits their ability to remember them all. So it is necessary to keep choices pertinent and parsimonious. | D: It is good to differentiate between a novice user and an expert user by keeping track of the number of interactions that the user has with the device, and tailoring an audio experience for first-time users, while playing shortened prompts to expert users.
